fps drops

i have this issue in some rooms where deppending on the direction im looking fps drop a lot. Searching for solutions i got to the gl_wireframe 2 command and i found out that the cause is that im watching a whole other room that im not supposed to see, and that is not accessible from there (trigger_teleports are used between rooms)


how do i fix this?

they are func_wall and have null texture on the other side. I've already fixed it by updating zhtl tools and changing walls and blocks to func_detail, which arent rendered
